The wall of a cold storage is made up of four layers; concrete, brick, cardboard and paint with respective thickness of 5, 60, 8 and 1 mm, and their corresponding thermal conductivities are 0.8, 0.7, 0.04 and 0.15 W m⁻¹ K⁻¹. The overall resistance of the wall to conduction heat transfer in m² K W⁻¹ is
Correct : 0.3
